Of the history of Britain during the century succeeding the Cæsarian expeditions we have some fairly satisfactory glimpses. The terror of Cæsar was sufficient, on the one hand, to prevent the British chiefs from interfering in Gallic affairs. It also appears to have deterred Caswallon from again attacking the philo-Roman Trinobantes, for numismatic evidence shows that they were independent at a much later epoch. But it does seem certain that it helped forward British unity, since we find a tendency to form groups or ‘empires’ that certainly included more than one tribe. One of these was founded by Commius the Atrebatian. He had taken sides with his countrymen against Cæsar in the last great Gallic uprising, and, after some remarkable adventures, had escaped to his kinsmen in Britain. By then he appears to have been acknowledged as king; at any rate, coins have been found bearing his name in what is known to have been the territory of the Atrebates. He and his sons extended their rule over the Cantii, the Regni of Sussex, and over some at least of the small clans known as Belgæ. Meanwhile, north of the Thames, the Catuvellauni was recovering from the effects of Cæsar’s invasion. It is at least possible that the discovery of rich gold-mines had something to do with their undoubtedly rapid rise in power. At any rate, Tasciovan, very probably the successor of Caswallon, coined most extensively in gold, silver, and bronze, and his widely-diffused coins show strong traces of Roman influence. His capital was certainly Verulam (St. Albans), since on most of his coins the Latinized name of the place figures. The Cantii and Trinobantes, however, still appear to have been the most civilized peoples of Britain. Tasciovan perhaps initiated a policy of aggression upon the Commian kingdom, and his son, Cunobelin, extended his sway over the entire south-east and south. The Iceni (Norfolk) and the Damnonii (Somerset, Devon, Cornwall) appear to have kept their independence, but may have paid tribute; and the Silures of South Wales were probably in Cunobelin’s sphere of influence. His capital seems to have been not his father’s Verulam, but the Trinobantian Camulodunum (Colchester).
